POST-BUCKLIXG ANALYSIS OF RESTRAINED LIP PLATE UNDER UNIFORM COMPRESSION

This paper is concerned with the rectangular plate loaded under uniaxally uniform compression with the unloaded edge rotationally restrained and the other edge stiffened. By means of nonlinear analysis the post-buckling stiffness is obtained. The influences of lip width, length to width ratio of plate and edge restraint against rotation on post-buckling are studied.
